TO ALL WHOM IT MAY CONCERN:

Be it known that I,"JAC OB BEXT'Z, of the city of Brooklyn, in the county. of Kings, and State of New York, have made certain new and useful Improvements in Machines for .Framing Match-,splints for Dipping; and I do -hcreby declare that tho-following is a full, clear, and exact description of the construction and operation of the same, reference being had to theannexed drawings, making part of this specification, in which- Figure 1 representsa front view of my improved machine; the position On the right-hand side being shown biscctd to exhibitsome of its working parts.

Figure 2 is a vertical-longitudinal central section of the same.-

Figure 3 isa top viewl of the same, the rear boing shown'rcmovcd.

Figure 4 isa detached side view of the working parts used for operating the feed.

Figure 5 is a detached perspective view of one side of thc groovcd bed, thc plunger-frame or comb and the working parts usedv for operating the feed of the splintsclampsor slats into the machine.

Similar letters of-reference indicate corresponding parts in the several figures.

The improvements herein shown appertain or relate more pa-rticularly'to a machine for framing matchsplints, patented by me June 26, 1866; and the rst part of my invention consists in the employment of a device for feeding the splint-slats into the machine as they are required for being filled with splints; the second part of my improvement'consists in providing the cam-bar plunger-frame with cams on cach side, and having doublencting levers attached to the machine, which are connected with the said feeding device, whereby/ an automatic feed of the splint-clamps or slats into the machine is obtained with a harmonious and positive action of and with the operation of the' machine; the third'part of' my improvement consists in providing the grooved bed, which is used to separate and receive tho splints from the hopper into its grooves, with a'ver'tical slot or opening near the forward part, along the inside of the hopper and across all of the grooves, whereby broken splints, or splints lying across the grooves-of theibed, are allowed to escapcor4 are made to discharge through said'opening from under the hopper, while and with the operation of and without stopping the machine.

To enable others skilled inthe art to make and use my improvement, I will proceed to describe the const-rue tion and operation of the same. l

The hoppers A, with the loose hopper B, shown in figs. 2 and 3, are madeto vibrateover the grooved bed C tc fill the grooves D oi`- the grooved bed' with splints,-from whence the said splints are delivered by means of the plnngers or comb D E passing through the grooves D of the said bed and thrust upon or into the grooves fthe splint-sint F in front of the said bed. The slide G stops successively for every stroke of the plungers and receives anew charge of splints. All the above is made and operated in a similar manner to that shown by me in my former machines, but now, instead of furnishing the splint-clamps or slatsl one at a time upon the slide G, until a splint-frameisiilled and completed, anclvthus made ready for dipping, I employ two vertical guide-posts H H, secured to the frame of thc machine, above, on each side of, and in line with the slide G, each of which guideposts is furnished with aver'tical grdove, I, of proper dimensions'to guide and allow the ends of the splint- .clamps orfslats to pass or drop freely through said groove I down uponAslideG. In the upper part ofthe groove I, in each post H, is hinged a friction-pawl, J, and a. pawl, K, is located in ,its rear, hung .o n the same fulcrum, andarrangedon the outside ofthe post Hf The end of this'pawl K is parted in two and bent at right angles so as to project and touch upon the" rear end of thesaid pawl J, andis pressed upon said pawl by means of a spring, L, secured on the outside of the post H, so that when the splint-clamps-:ire placed in the grooves I I the same are held from dropping down by means of the friction caused on their ends in passing 'the pawls J J, one each side of the posts H I-I. A third pawl, M,`is1hinged tothe outside of the lower part of each post H, the end of which-projects upward to within a distance equal to the thickness of the splint-clamps of thelends of the pawls Y J and K, and is bent over Vto project Valso a short distance into the groove I through o slot, N,- made in the lpost H for the purpose 'of arresting the splint-clamps when dropped into it.` A spring, O, presses upon .the rear of this pawl M. Non', Vbetween the ends of thesepawls K 'and M, in euch post, is arranged, inpropor bearings, a horizontal rockjshaft, P, provided with two short radial armsp and p', which radial arms are opposite each other, in such a manner that 'by the vibration of Athe rock-shaft P in one direcition` therarmlp engages the pawl M and draws its end from projecting into the groove I, and -by its vibrationf'in an opposite direction theA arm p' engages the pnwl -K and Withdra-ws'the lntter from pressing on the friction-pnwl J. Eeeh of theroek-shnfts I P is pro', vided with a. crank on its outside end, and invorder to transmit motion to the said rock-shaft P from the moving parts of the machine I employ n heut lever, R, on each side of the machine, having its centr-.il fulcrum 1' fixed in the frame, and provide each of the corresponding sides of the plunger-frame with n. cil-m, S, shown in figs. 4 and 5, so that et each end of the. motion of the plungers or comb E, the snidenm S is brought in eonttct with one of the ends of the lever E, whereby the said lover is vibrat'ed; nud by means of :m adjustable connectingrod, T, pivoted to the crunk Q and the rock-shaft P, and pivoted also to the outer end of the lever R, the said vibratory motion is'transferred from the plunger-freine to the rock-shaft l). l

When the machine is in operation u, nintnberoi` splint-clamps areplneed horizontally between the guideposts HH and inserted in the top of the grooves I I, and the .same ure nrrested upon the projections of the pawls M M As soon :is the plunger-frame and plungers'nre nearly being pressed back to the end of its back motion the cams S S operate upon the inner endtol; the levers R R and the nrm p l of the roclc-shft PP, releasing the pnwls K K, whereby the pewls J J nrc forced to clump the splint-slats, which is next to the lowest, while at the seme time the arms pp of the said rock-shafts operate against the pnwls M Mend withdrew their projections, and the rests oi' the lowest splint-clamp or' slnt'nre withdrawn thereby, und in consequence the said splint-clampl drops down upon the' top' of the splint-clump, which rests upon the slide G,'es shown in tigsfl und 2, the said-slide having been lowered in the usunl way by the sanne buch motion of the plunger-frame. On thc return or-forward motion of the plunger-frnme the Vearns S come again in Contact with the levers R nt their outer ends, and move the sii-mc back to their former position, whereby the pztwls M M nre'nmie to project into the grooves I I, and the pressure upon the pnwls J J is withdrawn, whereby the whole of the splint-elumps arbore' drop and rest upon the projeetionsot' the pawls M M until the lowstof tbcm is again delivered upon the slide G by the same operation of the backward motion of the plunger-frame es before described. Instead of haring a portion of the groored bed C hinged or parted to allow the escape of broken splints, or splints interfering with the proper operation of filling ,the grooves of the some from ltime to time, I employ one complete solid bed, which is provided with n. narrow slot, U, cut through it, und extending across its grooves underlthe forward part of the hoppers immediately behind the usual scraper V on the forward lower edge of 'theloose hopper B, ns shown in figs. 2, 3, :1nd 5. By means ot' this slot U a proper and continuous escape for broken splints, or splints interfering with the proper filling of the seidgrooves in the heil C, is readily obtained by operating the hoppcrs und-plungers, whereby the operution of the machine is considerably facilita-ted, nnd is rendered continuous.

What I claim as my invention, and desire to secure by Letters Patent, is4

l1. The employment of n. splint-clamp feeding device, arranged to work in connection with the machine for framing and fillii'ig the splint-clamps with splits, substantially as and for the purpose herein shown.

2. The employment of the cams S S, the levers R- R, and' connecting-rods T T', for the purpose of automatically operating the said feeding device, with the operation ofthe framing and filling ofthe splint-frames, substantizilly aslrierein shown.

3. The employment of the slet U, in connect-ion with thel grooved bed C :und hopper B und plungers or comb E, substantially ns :rnd for the purpose herein described.
